indirubin-5-sulfonate

Indirubin-5-sulfonate shows inhibitory activity against GSK-3β. Indirubin-5-sulfonate is a cyclin-dependent kinase (CDK) inhibitor, with IC50 values of 55 nM, 35 nM, 150 nM, 300 nM and 65 nM for CDK1/cyclin B, CDK2/cyclin A, CDK2/cyclin E, CDK4/cyclin D1,

5-Iodo-indirubin-3'-monoxime is a potent GSK-3β, CDK5/P25 and CDK1/cyclin B inhibitor, competing with ATP for binding to the catalytic site of the kinase (IC50s: 9, 20 and 25 nM).

Indirubin-3'-monoxime-5-sulphonic acid is a potent and selective inhibitor of GSK-3β, CDK5, and CDK1 with IC50s of 80nM,5 nM, and 7 nM, respectively.
